Voltage reference refers to a circuit or component that provides a reference voltage. In its simplest form, a voltage reference can be a precise, stable diode or zener diode operated at its precise breakdown voltage. More complex designs may use band gap references or sophisticated IC circuitry. The REF1004I-2.5 is a voltage reference IC from Texas Instruments’ industry-leading portfolio of precision linear voltage references.
